These bolts shall be a minimum of 5/8-inch diameter and shall extend a minimum of 3-3/4 inches into the concrete floor. Spacing between bolts shall be on maximum 24 inch centers. The aisle entries shall have bolt spacing no greater than 8 inches apart extending at least 3 feet into the aisle. If cutting a rail to length leaves no anchoring holes within 8 inches of the cut end, then the Contractor shall drill a new hole and install a bolt 2 inches from the end. Joints where two rails are butted together shall have mounting plates on the back side to which both rails are bolted. The bolt holes in the rails shall be recessed so that the bolt heads are flush with the rails.

autonumlgl Fork rotation The carriage shall traverse to permit the forks to rotate and move laterally across the width of the load handler while within a storage aisle. The forks shall rotate 180 degrees on a vertical axis at any height such that the forks face either side of the aisle.

autonumlgl Fork dimensions Forks shall be minimum 3-1/2 inches wide by 36 inches long, forged steel. The forks shall be a minimum 1-1/4 inches thick at the heel and taper to a minimum 1/4 inch thick at the tip. Fork spacing shall be adjustable.

autonumlgl Wheels Wheels shall clear the truck structure by at least 1/4 inch under all conditions of operation. All tires shall be non-marking, solid polyurethane or non-marking, solid rubber molded onto a steel band pressed onto flat-faced wheels.

autonumlgl Auxiliary lowering control The trucks shall have an auxiliary lowering control to lower the lift platform to ground level in case standard lowering procedures have failed. The control shall be accessible from ground level.

autonumlgl Operator's compartment The operator's compartment shall raise and lower on the primary mast. The compartment shall provide the operator with an unobstructed view of the forks, load, and pallet rack beams at all heights, and particularly during the storing and retrieval operation. The operator's compartment shall be designed for unobstructed egress from the compartment while in the storage aisle. A nonskid, low-fatigue surface or mat shall be provided for the floor.

autonumlgl Overhead guard The operator's compartment shall be protected by a steel overhead safety guard which meets the requirements of ANSI B56.1A.

autonumlgl Side rails Side rails for operator restraint shall be in accordance with ANSI B56.1A. The truck shall not operate unless the side rails are in the down position. The side rails shall be hinged so that they can be raised and locked in the raised position.
